Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1718371 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Identical current rating (41A IEC), voltage rating (1 kV IEC), and wire gauge range (8-24 AWG / 0.2-10mm²)
Mechanical Compatibility: Matching pitch (0.300" / 7.62mm), position count (2), termination style (screw-type rising cage clamp), and mounting configuration (free-hanging in-line)
Material & Safety: Equivalent housing material (Polyamide/Nylon), flammability rating (UL94 V-0), and contact finish (tin)
Regulatory Compliance: RoHS and REACH compliance status

The Phoenix Contact 1778065 meets all substitution criteria as an active equivalent model within the COMBICON PC series.

Engineering Selection Recommendations

The Phoenix Contact 1778065 is the direct active equivalent for the obsolete 1718371 model. Both components share identical electrical ratings, mechanical specifications, and termination characteristics within the COMBICON PC series.

Status Advantage: The 1778065 carries active product status with higher current inventory availability (2351 pcs vs. 868 pcs), ensuring supply chain continuity.

Compliance: Both parts maintain UL94 V-0 flammability certification and REACH compliance. The 1778065 carries ROHS3 certification, representing current regulatory alignment.

Physical Consideration: The 1778065 features a reduced insulation height (0.776" vs. 0.902"), which may affect mechanical fit in applications with tight vertical spacing constraints. Verify mounting clearance in your specific application geometry.

Torque Specification: The 1778065 torque range (0.5-0.8 Nm) encompasses the 1718371 specification (0.7-0.8 Nm), maintaining compatibility with existing assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1778065 directly replace the 1718371 in existing assemblies?

A: Yes, the 1778065 is electrically and mechanically equivalent. Both components support identical current (41A), voltage (1 kV IEC), wire gauge (8-24 AWG), pitch (7.62mm), and termination methods. Verify that the reduced insulation height (19.70mm vs. 22.90mm) does not conflict with your mechanical design.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1778065 is in active production with established supply chains, whereas the 1718371 is obsolete and subject to inventory depletion. Transitioning to the 1778065 ensures long-term component availability and reduces procurement risk.

Q: Are there differences in screw torque specifications between these parts?

A: The 1718371 specifies 0.7-0.8 Nm torque, while the 1778065 allows 0.5-0.8 Nm. The 1778065 range is broader and fully encompasses the original specification, maintaining assembly compatibility.

Q: Do both parts meet current regulatory requirements?

A: Both components are RoHS and REACH compliant. The 1778065 carries ROHS3 certification, representing alignment with current regulatory frameworks. Both maintain UL94 V-0 flammability ratings.

Q: What packaging differences exist between these parts?

A: The 1718371 is supplied without specified packaging, while the 1778065 is packaged in bulk format. Confirm bulk packaging compatibility with your receiving and inventory management procedures.

Q: Are there any wire entry or mounting orientation differences?

A: No. Both components feature identical 180° free-hanging in-line wire entry and mounting configuration, ensuring drop-in compatibility in existing connector assemblies.
